When you define a new site in Site Maintenance (1.1.13), you must associate it with a domain. When a site is associated with the current working domain, it is considered a primary site; otherwise, it is a connection record pointing to the domain where the actual site-related data is maintained. The other domain can be in this database or in another connected database.

When you are using multiple databases operating over a network, the system uses the domain associated with a site to determine where database records should be updated.

To help you manage the relationships among sites and domains, you can optionally create connection records in related domains when you create a new primary site.
